The former acquired a snap vnode lock while holding sd_lock while the
latter does the opposite.
The solution is drop sd_lock before acquiring the vnode lock. That
should be okay as we are still holding a lock on the 'snapshot'
directory in the exclusive mode. That lock ensures that there are no
concurrent lookups in the directory and thus no concurrent mount attempts.
But now we have to account for the possibility that the snap vnode
might get reclaim after we drop sd_lock and before we can get
the node lock. So, check for that case and retry.

This should fix the build on older stable/10, since install is a bootstrap
tool.
Pending a decision how to fix this properly, revert utimensat usage. Copies
with the -p option will again appear older than the original almost always,
but -p is not commonly used.
This commit partially reverts r273641 which introduced the leak.
It did so to accomodate for some consumers of traverse() that expected
the starting vnode to stay as-is. But that introduced the leak in the
case when a mounted filesystem was found and its root vnode was
returned.
r299914 removed the troublesome consumers and now there is no reason to
keep the starting vnode. So, now the new rules are:
- if there is no mounted filesystem, then nothing is changed
- otherwise the starting vnode is always released
- the root vnode of the mounted filesystem is returned locked and
referenced in the case of success

Add a new get_id interface to pci and pcib. This will allow us to both
detect failures, and get different PCI IDs.
For the former the interface returns an int to signal an error. The ID is
returned at a uintptr_t * argument.
For the latter there is a type argument that allows selecting the ID type.
This only specifies a single type, however a MSI type will be added
to handle the need to find the ID the hardware passes to the ARM GICv3
interrupt controller.
A follow up commit will be made to remove pci_get_rid.

We pretend that snapshots mounted under .zfs are part of the original
filesystem and we try very hard to hide vnodes on top of which the snapshots
are mounted. Given that I believe that the removed operations should
never be called. They might have been called previously because
of issues fixed in r299906, r299908 and r299913.

This is a bit hackish, but the flag is currently set only for ZFS
snapshots mounted under .zfs. mountcheckdirs() can change cdir/rdir
references to a covered vnode. But for the said snapshots the covered
vnode is really ephemeral and it must never be accessed (except
for a few specific cases).
To do: consider removing mountcheckdirs() entirely

Previosuly we did that only if the snapshot was mounted earlier, its
root vnode got recycled and then we accessed it again.
We never cleared the flag for a freshly mounted snapshot.
That was very inconsistent and probably a source of some bugs.
Or maybe that painted over some bugs which might get revealed now.
We should consistently clear the flag because we try very hard to
pretend that snapshots auto-mounted under .zfs are part of their
original filesystem. In other words, we try to hide the fact that they
are different filesystems / mountpoints.

The logic is similar to that already present in zfs_dirlook() to handle
a dot-dot lookup on a root vnode of a snapshot mounted under
.zfs/snapshot/.
illumos does not have an equivalent of vop_vptocnp, so there only the
lookup had to be patched up.

* Remove excessive references on a snapshot mountpoint vnode.
zfsctl_snapdir_lookup() called VN_HOLD() on a vnode returned from
zfsctl_snapshot_mknode() and the latter also had a call to VN_HOLD()
on the same vnode.
On top of that gfs_dir_create() already returns the vnode with the
use count of 1 (set in getnewvnode).
So there was 3 references on the vnode.
* mount_snapshot() should keep a reference to a covered vnode.
That reference is owned by the mountpoint (mounted snapshot filesystem).
* Remove cryptic manipulations of a covered vnode in zfs_umount().
FreeBSD dounmount() already does the right thing and releases the covered
vnode.
